Description
Die Erfindung bezieht sich auf eine Leuchteinrichtung für Schienenfahrzeuge, mit einem in einem Gehäuse angeordneten Leuchtdiodenfeld und einer eine offene Seite des Gehäuses verschließenden Abdeckung, die für von dem Leuchtdiodenfeld erzeugte Lichtstrahlung transparent ist. The invention relates to a lighting device for rail vehicles, with a arranged in a housing light-emitting diode array and an open side of the housing occlusive cover, which is transparent to light radiation generated by the light emitting diode array.
Im Stand der Technik ist eine solche Leuchteinrichtung bekannt, und zwar z. B. von der S-Bahn DB-Baureihe ET 430. Eine solche Leuchteinrichtung hat ein Leuchtdiodenfeld, welches mit Hilfe von Schrauben auf einer Gehäuseinnenseite angebracht ist. Dazu müssen in einer Platine des Leuchtdiodenfeldes Bohrungen vorgesehen werden, so dass die Platine an dem Gehäuse fixierbar ist. Der Kontakt zwischen der Platine und dem Gehäuse ist auch insofern von Bedeutung, dass durch den Betrieb des Leuchtdiodenfeldes auftretende Wärme in das Gehäuse abgeführt wird. Dazu ist das Gehäuse typischer Weise metallisch. Im Anwendungsbereich bei Schienenfahrzeugen wird das Gehäuse häufig als Strangpressprofil, insbesondere aus Aluminium, vorliegen. In the prior art, such a lighting device is known, namely z. B. of the S-Bahn DB series ET 430. Such a lighting device has a light-emitting diode array, which is mounted by means of screws on a housing inside. For this purpose, holes must be provided in a circuit board of the light-emitting diode array so that the circuit board can be fixed to the housing. The contact between the board and the housing is also important in that heat occurring by the operation of the LED array is dissipated into the housing. For this purpose, the housing is typically metallic. In the application of rail vehicles, the housing will often be present as an extruded profile, in particular aluminum.
Insgesamt wird die Art der Befestigung des Leuchtdiodenfeldes in dem Gehäuse als aufwändig angesehen. Zudem hat die punktuell wirkende Befestigung des Leuchtdiodenfeldes am Gehäuse die Eigenschaft, dass im Wesentlichen nur an diesen Stellen eine Wärmeableitung von dem Leuchtdiodenfeld in das Gehäuse hinein stattfindet. Overall, the type of attachment of the light-emitting diode array in the housing is considered to be expensive. In addition, the point-effect attachment of the light-emitting diode array on the housing has the property that substantially only at these points, heat dissipation from the light-emitting diode field into the housing takes place.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die eingangs genannte Leuchteinrichtung für Schienenfahrzeuge derart weiterzuentwickeln, dass gleichzeitig eine einfach handhabbare Befestigung eines Leuchtdiodenfeldes am Gehäuse ermöglicht, aber auch gute Ableiteigenschaften geschaffen werden. Proceeding from this, the present invention seeks to further develop the above-mentioned lighting device for rail vehicles such that at the same time allows easy handling of a light-emitting diode array on the housing, but also good Ableiteigenschaften be created.
Diese Aufgabe wird bei der Leuchteinrichtung dadurch gelöst, dass das Gehäuse langgestreckt ausgebildet ist und einen allgemein U-förmigen Querschnitt aufweist, wobei das Leuchtdiodenfeld auf der der offenen Seite gegenüberliegenden Seite des Gehäuses angeordnet ist und mittels eines die Abdeckung bildenden, langgestreckten, elastischen Clips gegen das Gehäuse gepresst ist. This object is achieved in the lighting device in that the housing is elongated and has a generally U-shaped cross-section, wherein the LED array is disposed on the opposite side of the open side of the housing and by means of the cover forming, elongated, elastic clips against the housing is pressed.
Mit Hilfe des langgestreckten, elastischen Clips wird nunmehr das Leuchtdiodenfeld nicht nur punktuell sondern über eine größere Strecke entlang des Gehäuses an das Gehäuse angepresst, so dass sich günstige Wärmeableiteigenschaften ergeben. Zudem kann auf die im Stand der Technik gebräuchlichen Schraubverbindungen für Befestigungszwecke verzichtet werden. Die Montage der Leuchteinrichtung, beispielsweise in Schienenfahrzeugen, wird somit vereinfacht. With the help of the elongated, elastic clip, the light-emitting diode array is now not only selectively pressed against the housing over a greater distance along the housing, so that favorable heat dissipation properties result. In addition, can be dispensed with the usual in the art screw for fastening purposes. The installation of the lighting device, for example in rail vehicles, is thus simplified.
Der Clip kann aus elastischem Kunststoffmaterial hergestellt und an dem Gehäuse abgestützt sein. Beispielsweise kann das Gehäuse an seiner offenen Seite Führungsnasen aufweisen, an denen der Clip abgestützt ist. Durch die Elastizität des Clips wird es ermöglicht, dass das Leuchtdiodenfeld an die der offenen Seite des U-förmigen Gehäuses gegenüberliegenden Seite angepresst wird. The clip can be made of elastic plastic material and supported on the housing. For example, the housing may have guide lugs on its open side, on which the clip is supported. The elasticity of the clip allows the light-emitting diode array to be pressed against the side opposite the open side of the U-shaped housing.
Der Clip kann in dem Gehäuse bogenförmig verlaufen und an seinem der offenen Seite des Gehäuses entferntesten Abschnitt gegen das Leuchtdiodenfeld drücken. Bei dieser Ausführungsform wird gleichzeitig eine sichere Befestigung des Leuchtdiodenfeldes und ein günstiger Wärmetransport von dem Leuchtdiodenfeld zum Gehäuse bewirkt. The clip may be arcuate in the housing and press against the light emitting diode array at its most distal portion of the housing. In this embodiment, a secure attachment of the LED array and a favorable heat transfer from the LED array to the housing is effected simultaneously.
Der Clip kann bevorzugt aus Polykarbonat hergestellt sein. Dieses Material zeichnet sich durch günstige Eigenschaften im Hinblick auf die Durchlässigkeit für von dem Leuchtdiodenfeld erzeugtem Licht aus. The clip may preferably be made of polycarbonate. This material is characterized by favorable properties with regard to the transmittance of light generated by the LED array.
Außerdem erfüllt es die Erfordernisse im Hinblick auf eine Elastizität, die für das Anpressen des Leuchtdiodenfeldes an das Gehäuse erforderlich ist. In addition, it meets the requirements for elasticity required for pressing the LED array to the housing.
Das Gehäuse kann bevorzugt von einem Strangpressprofil, beispielsweise aus Aluminium, zum Einbau in ein Schienenfahrzeug gebildet sein. Dieses Strangpressprofil kann beispielsweise Teil einer Gepäckablage oder Deckenteils des Schienenfahrzeugs sein. The housing may preferably be formed by an extruded profile, for example made of aluminum, for installation in a rail vehicle. This extruded profile may for example be part of a luggage rack or ceiling part of the rail vehicle.
Es ist hervorzuheben, dass der Clip aus elastischem Material in Längsrichtung des Gehäuses nicht notwendiger Weise über das gesamte Leuchtdiodenfeld verlaufen muss. Zwar ergibt sich bei vollständiger Überlappung zwischen dem elastischen Clip und dem Leuchtdiodenfeld eine bestmögliche Wärmekopplung zwischen dem Leuchtdiodenfeld und dem Gehäuse. Soweit es ein Betrieb des Leuchtdiodenfeldes jedoch zulässt, kann auch eine Mehrzahl an Clips zur Befestigung des Leuchtdiodenfeldes verwendet werden, die dann wahlweise entlang des Gehäuses angeordnet sein können. It should be emphasized that the clip of elastic material in the longitudinal direction of the housing does not necessarily have to run over the entire light-emitting diode array. Although the overlap between the elastic clip and the light-emitting diode field results in the best possible heat coupling between the light-emitting diode array and the housing. However, as far as an operation of the light-emitting diode array permits, a plurality of clips can also be used for fastening the light-emitting diode array, which can then optionally be arranged along the housing.

Die einzige Figur zeigt eine Querschnittsansicht einer Leuchteinrichtung für Schienenfahrzeuge. An embodiment of the invention will be explained in more detail with reference to the drawings.
